Japanese Toilets: Buttons, How to Use Them and Why Visitors Love Them
Updated: Oct 25
Short answer: a Japanese toilet may combine a normal flush toilet with an optional warm-water bidet seat. Find Stop and Flush first, sit normally, and use only the functions you want.
You do not need to press every button. This guide separates the features visitors enjoy from the controls that actually clear the bowl—and explains what changes when you encounter a simpler toilet or a squat toilet.
Why do so many visitors like Japanese toilets?
The appeal is practical, not just futuristic: a warm seat instead of a cold surprise, water cleansing with adjustable settings, optional drying and a sound feature that can make a shared restroom feel more private.
There is evidence of interest, but it needs context. A TOTO release published in March 2024 reported that about 88% of respondents wanted warm-water cleansing seats in toilets used while traveling in Japan.
The manufacturer's online survey took place in 2023 and covered 1,000 recent Japan travelers across selected markets. Respondents also intended to visit again. It was not a census of all overseas visitors.
Among the reported reasons, wanting to feel clean after using the toilet and avoiding a cold seat stood out. That helps explain the enthusiasm without claiming that everyone likes the spray or every Japanese restroom is spotless.
Think of comfort and choice rather than a health promise. A heated seat does not establish cleanliness, and an elaborate control panel does not guarantee an accessible or well-maintained room.
Japan versus home: compare the toilet, not whole countries
Electronic bidet seat: a sit-down toilet with water-cleansing controls, often on a side panel or wall remote. Heated seats, dryers, lid controls and other extras depend on the model.
Plain sit-down toilet: a familiar bowl and seat without the electronic washing functions. There may still be a lever, wall button or sensor for flushing.
Japanese-style squat toilet: a floor-level fixture used in a squatting position. It is not a toilet seat to sit on.
JNTO's toilet overview describes both electronic features and traditional squat toilets. Japan does not have one universal setup; hotels, stations and individual cubicles can differ.
Nor is “overseas” one toilet culture. You may already know a separate bidet, a handheld spray or an electronic seat from home. The useful difference is which functions are integrated into the particular fixture in front of you.
The button names worth recognizing
Read words and symbols together; do not rely on color alone. The Japan Sanitary Equipment Industry Association's standard pictograms are a useful reference, but older panels and individual models still vary.
止 / 停止 — Stop: stops cleansing or another active function as indicated on that model. It does not flush the bowl.
Reading: tome / teishi (stop).
おしり — Rear: starts rear cleansing. ビデ — Front/Bidet: starts front cleansing. These are body-washing controls, not two kinds of toilet flush.
Reading: oshiri (rear); bide (front/bidet).
水勢 / 水圧 — Water pressure: adjusts the spray strength, often with plus/minus buttons. 洗浄位置 — Position: adjusts where the spray reaches.
Reading: suisei / suiatsu (water pressure); senjō ichi (spray position).
温水 — Water temperature and 便座 — Seat temperature are different settings. Avoid changing a shared toilet's preferences unnecessarily.
Reading: onsui (warm water); benza (toilet seat).
乾燥 — Dryer: optional warm-air drying. 音 / 音姫 — Sound: a privacy sound or related sound control; the precise wording varies.
Reading: kansō (dryer); oto / Otohime (sound/privacy sound).
流す / 洗浄 — Flush: look for the bowl-flushing label or symbol. 大 / 小 commonly distinguish full and light flushes, not strong and weak bidet sprays.
Reading: nagasu / senjō (flush); dai (full flush); shō (light flush).
TOTO's illustrated visitor guide separates these functions. “WASHLET” is TOTO's trademark; other manufacturers make electronic bidet seats too.
How to use an electronic bidet seat calmly
Before starting: locate the actual flush control, Stop and toilet paper. Check the seat is ready, then sit on the seat normally—never stand or squat on a sit-down toilet.
For optional cleansing: remain seated, select the appropriate rear or front function and begin with low pressure. Adjust gently if needed, then press Stop before getting up.
To finish: dry with toilet paper or use the dryer if available and wanted. Check how this particular toilet flushes, operate it as directed, and make sure the bowl is clear for the next user.
TOTO's RG/RG Lite quick-start guide illustrates Stop, cleansing, pressure and position adjustments for those models. It is an example, not an exact map of every toilet in Japan.
Do not test the spray while standing beside the bowl or try to defeat a seat sensor. Skip the washing functions if you prefer; using the toilet does not require trying the bidet.
Flush, flushing sound and emergency call are different
The flush may be a tank lever, a wall button, a button on the bidet remote or a hand-hover sensor. Some models flush automatically after you stand. Follow the displayed instructions rather than assuming every sensor does the same job.
A water sound is not proof of a flush. Privacy devices imitate running water; they do not necessarily clear the bowl. Look for the actual flushing control and check the result before leaving.
非常 / 呼出 / SOS — Emergency call: this is for requesting help, not an alternative flush. Never test it out of curiosity; use it when you genuinely need assistance.
Reading: hijō / yobidashi (emergency/call for help). SOS uses the letters S-O-S, not a Japanese word.
The industry's toilet-use guide explains these separate devices. A call button can be near the flush control, so read the label before pressing.
Can you flush toilet paper in Japan?
For an ordinary Japanese flush toilet, the supplied toilet paper normally goes into the bowl and is flushed. If your usual routine at home involves a paper bin, do not automatically transfer that habit here.
Do not put sanitary products, diapers, paper towels or ordinary facial tissues into the bowl. Keep wet wipes out unless the particular facility explicitly permits that product; a packet's marketing is not a substitute for the site's instructions.
TOTO's flushing precautions warn that foreign objects and excessive toilet paper can block the toilet. Use a sensible amount and follow the fixture's full/light-flush instructions.
Special facilities can have different disposal rules. Read the signs, use the appropriate waste bin and ask staff if unclear. If water is rising or a blockage is apparent, do not keep flushing.
If the cubicle has a squat toilet
Follow its diagram: on the usual Japanese-style fixture, face the raised hood and squat over the bowl with your feet on either side. Tokyo's visitor-manners booklet illustrates the direction. Keep clothing clear of the floor and fixture.
Do not sit on the hood or stand on a Western-style seat to imitate this position. If squatting is unsuitable for you, look for a sit-down cubicle or ask where one is available.
Choosing a different fixture is a practical decision, not a failure to appreciate local culture. Check before settling into a queue if the type of toilet matters to you.
Small habits that make restroom stops easier
Check for paper and supplies before using the cubicle. Carrying a small hand towel can be useful; hand-drying equipment and amenities vary. Plan a comfortable stop before a long activity rather than assuming the next small shop allows toilet access.
If a spray does not start, check the instructions and whether you are seated normally. Do not pull out the nozzle, remove the remote, unplug equipment or alter plumbing in a public restroom. Ask staff for help.
Need help? Show one of these phrases: “トイレはどこですか？” (Toire wa doko desu ka?) means “Where is the restroom?”
“どのボタンで流せますか？” (Dono botan de nagasemasu ka?) means “Which button flushes the toilet?” “トイレが流れません。” (Toire ga nagaremasen.) means “The toilet will not flush.”
Need extra space, a changing table or particular accessibility features? Ask about the facility you will use; a bidet button panel alone tells you nothing about the whole room's accessibility.

FAQ
Do all Japanese toilets have heated seats and bidets?
No. Electronic seats, plain sit-down toilets and squat toilets can all occur. Specific features vary even between models in the same building.
Can I use the toilet without pressing the washing buttons?
Yes. The bidet and dryer are optional. Use toilet paper, follow the local disposal instructions and flush the bowl normally.
Is the small flush button the same as a gentle spray?
No. A light flush clears the bowl with a smaller flush. Spray pressure is a separate cleansing adjustment. Identify the function by its label and symbol.
